Summary: The detection of anomalously strong basal reflectivity beneath the Martian South Polar Layered Deposits (SPLD) has led to hypotheses suggesting the presence of basal materials such as liquid water. By analyzing existing data, we found that a certain percentage of the Martian surface could produce basal reflections similar to SPLD measurements under the assumption of impure ice. To prevent bright SPLD-like basal reflections, an ice loss tangent > $ > $0.01 is required. The detected bright terrains are mainly located within volcanic constructs of different geological epochs.

Summary: A new Martian dust simulant JMDS-1 was reported, showing similar properties to Martian dust detected by Mars rovers, while having a thermal conductivity two times lower than sub-millimeter sized soil simulant. This suggests that the dust layer on Mars plays a significant role in changing the thermal properties of surface materials.

Summary: In this study, the thermal conductivity of CO2 at different pressures was determined using experimental measurements and first-principles calculations. The results show that the thermal conductivity of liquid and solid CO2 varies with pressure, which has significant implications for heat flow and temperature distribution in planetary and satellite interiors.

Summary: The presence of liquid water is crucial for habitability, and new research suggests that on icy exo-Earths outside the habitable zone, subglacial oceans of liquid water can form at the base and within the ice sheets due to geothermal heat flow. These subglacial oceans, shielded by thick ice layers, may provide habitable conditions for an extended period.

Summary: The presence of valley networks on Mars provides evidence for the existence of liquid water on the planet's surface. The characteristics of these valleys suggest that they were formed by subglacial channels, indicating that ice sheets may have played a significant role in shaping the Martian landscape even in a cold climate.

Summary: This study provides a detailed analysis of the physical and thermal properties of the South Polar Layer Deposits (SPLD) using data acquired by MARSIS. The frequency-dependent attenuation suggests that the SPLD are compositionally homogeneous at Ultimi Scopuli, and the results support the presence of perchlorate brines within liquid vein networks as the source of the bright basal reflections.

Summary: This review provides the first global inventory of subglacial lakes, outlining their settings, impacts, and potential changes with climate warming. Subglacial lakes have repositories of ancient climate conditions, provide habitats for life, and influence ice flow, basal hydrology, biogeochemical fluxes, and geomorphic activity. The behavior of these lakes is influenced by their subglacial setting and the mass balance regime of the overlying ice mass. Climate warming is predicted to reduce the number and size of subglacial lakes in regions with steeper ice surfaces, but increase activity with higher discharge drainages of shorter duration.

Summary: The Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) detected liquid water in the south polar region of Mars, sparking debate about the origin and stability of liquid water under present-day Martian conditions. New data confirmed the presence of a lake and suggested a complex hydrologic system, possibly composed of salty brines. The results indicate a liquid water body at Ultimi Scopuli and the presence of other wet areas nearby.

Summary: Heat flow measurements are crucial for understanding planetary interior composition and evolution. In the absence of direct measurements, estimating planetary heat flow can be done by modeling lithosphere response to stress. The estimation of low mantle heat flow in Mars suggests possible depletion of heat-producing elements in the Martian mantle.

Summary: Expanding on previous studies of the South Polar Layered Deposits' basal interface using Mars radar data, researchers found widespread occurrences of basal echo power exceeding the surface in the SPLD region. These high basal echo power signatures appear to be frequency independent in MARSIS data.

Summary: Recent findings suggest the presence of subsurface brine beneath the South Polar Layered Deposit on Mars, but other explanations for the strong radar reflections, such as contrast in electric conductivity, are also possible. This opens up new potential interpretations for the observed phenomena without requiring the presence of liquid brine.

Summary: The bright radar reflections observed beneath the south polar layered deposits on Mars were proposed to be caused by hydrated and cold clay-rich deposits, rather than liquid water. Experimental measurements and wave propagation modeling showed that these minerals, cooled to 230 K, have the potential to cause the bright reflections and are present in south polar orbital visible-near infrared reflectance spectra.

Summary: The heat flow and physical properties package (HP3) of the InSight Mars mission was designed to determine the martian planetary heat flow by measuring thermal conductivity and geothermal gradient in the subsurface. Results showed low thermal conductivity in the Martian soil, indicating minimal soil cementation and distribution of cementing agents like salts in grain coatings. Soil densities compatible with the measurements suggest soil porosities in a certain range.

Summary: By combining radar, gravity, and topography data with a flexural loading model, the study estimates the density, dielectric constant, and elastic thickness of the lithosphere beneath the south polar cap on Mars. The results suggest a maximum lithospheric flexure of 770 m, a potential 26% increase in the volume of the polar cap, and a surface heat flow lower limit of 23.5 mW m-2, indicating significant differences in thermal evolution between the north and south poles.
